Abstract

Using LS-DYNA software, impact response of submunitions drop on concrete was simulated and tested, with different drop angles and attack ones. The drop law of the maximum overload and the impact action time were obtained in the ranges of 60°~90° drop angles and less than 5° attack ones. The numerical simulation results agreed well with those of test. The study results were useful for establishing an impact response theoretical model of submunitions drop.
